Greetings all. I am converting a full size 40 BE to 357 sig, expecting the barrel by the end of next week. I was wondering if anyone could give me some input on the recoil spring. I believe the full size 40 is rated at 12 lbs and wanted to know what rating, if any, I should change to for the 357 sig. Any help would be appreciated. Thanks in advance.

I don't know the letter designation for the 357, but there is a listing by letter designation on Zahal's web site for the DSM recoil springs. That might let you know what are compatible (just a thought).

There actually is no letter designation for the 357, as it is not offered factory standard. Thanks for the thought though, I may end up just getting a dpm for the full size 40 and see how it functions.

I have been holding off on posting about it as my project is not quite complete, but yes, I am running an EFK ported Tanfoglio barrel in 357 sig FLAWLESSLY. No fitting required, all my mags work fine, using the DPM as well. I will post more about it within the next couple weeks, and there will be plenty of pictures.

Nice. Very jealous. I suspect that the Jericho is an awesome platform to shoot the 357 from. You have, by the way, invented the ultimate Zombie gun. Look forward to your write up and of course the obligatory pics.

Wait a week or two for the write up; after that it will be confirmed that zombies can run....away.
